NFORMATION

The Super X2 Practical MK I and MK II shotguns are
specialized versions of the Winchester Super X2 design

made specifically for practical shooting competition and

similar events. The design is built on the basic Super X2
platform with some differences. The Practical features an
extended magazine tube for larger magazine capacity. a
unique barrel with cantilever rear sight base and fold-down
sight on the MK I and a removable LPA sight on the MK II.

Some components, like certain surface areas of the magazine
tube, have been configured for heavy use. Your Super X2
Practical is supplied with one (1) Standard Invector

™

choke

tube, which is choked cylinder bore. Other tubes are avail-
able as accessories from your dealer.

This supplement addresses the unique features of the Super
X2 Practical only. General instructions and warnings are
contained in the complete Super X2 owner’s manual supplied
with your gun.

HAMBER

The Super X2 Practical has a 12 gauge, 2

4

" chamber. It is

designed to handle 2

3

⁄

section (“Ammunition and Gas Pistons”). This includes all
but extra-light loads.

The Super X2 Practical is NOT

designed to handle 3" or 3

AS

P

ISTONS

The Super X2 Practical is designed to fire 2

3

⁄

4

" shells only.

Both Practical shotgun models include two separate gas
pistons (Figure 1). The pistons are specifically configured
to handle the full spectrum of factory sporting shells and
2

3

⁄

" magnum loads. Always use the correct piston for the

ammunition being used. Using the incorrect piston may
cause malfunction and/or cause serious, unnecessary wear
on the action. Instructions for changing the pistons begin
on page 2.

EASSEMBLY

1. Insert the sleeve spring, gas sleeve and piston — in

that order — on the magazine tube as explained in the
complete Super X2 owner’s manual.

2. To reinstall the barrel, align the barrel with the magazine

tube and inset the gas bracket over the magazine tube and
slide rearward. Align components as explained in the
complete Super X2 owner’s manual. Be careful to position
the cantilever in alignment with the receiver before
the barrel extension reaches the receiver as you slide the
barrel rearward. It may require some careful positioning
the first time to learn how to line up all the components
as they come together.

3. With the barrel fully in the correct position replace the

forearm as shown in the complete Super X2 owner’s
manual, sliding it from the end of the magazine all the way
into position.

4. Insert the forward magazine sleeve onto the magazine

tube, flanged end first. This is the end with the
noticeable flange and a rectangular protrusion coming
from the flange.

5. Position the protrusion downward, in relation to the

barrel, where it contacts the front of the forearm. It will
drop into a matching recess in the front of the forearm
(Figure 3).

6. With the forward magazine sleeve in place, replace

the magazine cap. The barrel and gas system are now
fully reassembled.

YSTEM

All Super X2 Practical shotguns have a cantilever rear sight
rail for mounting optical, red dot or similar type sights.
Follow the instructions provided with any accessory sight to
install the sighting system.

The Practical MK I incorporates a fold-down rear sight
(Figure 4) located on the front of the sight rail. With the
rear sight in the “up” position the sight aligns with the fixed
front sight. When folded down, the lengthwise groove in the
cantilever can be used as a sighting plane, aligning with the
front fiber optic sight for extremely fast sighting situations.
The rear sight is adjusted for elevation using the two small
screws found on the rearward side of the rear sight. Loosen
them slightly and move the sight blade up or down to adjust
the sights. Move the blade up to move point of impact up.
Move the blade down to lower point of impact. Windage
adjustment is accomplished by moving the front (or rear)

ALWAYS PLACE THE SAFETY IN THE “ON SAFE”

POSITION BEFORE BEGINNING ANY WORK

ON YOUR SHOTGUN. CHECK YOUR GUN

CAREFULLY TO BE CERTAIN THAT THE

CHAMBER, FEED MECHANISM AND MAGAZINE

CONTAIN NO SHELLS. ALWAYS KEEP THE

MUZZLE POINTED IN A SAFE DIRECTION. READ

AND HEED THE SAFETY/WARNINGS SECTION IN

THE FIRST PART OF THE COMPLETE SUPER X2

OWNER’S MANUAL.

1.

Make sure your gun is fully unloaded. Keep the muzzle
pointed in a safe direction as explained in the complete
Super X2 owner’s manual.

2. Lock the action rearward.

3. Unscrew the magazine cap.

4. Remove the forward magazine sleeve from the

magazine by sliding it forward, off the tube.

5. Slide the forearm forward, fully over the extended

magazine tube.

6. Remove the barrel by pulling it forward — staying

in alignment with the magazine — until the
magazine bracket passes the end of the magazine.
Set the barrel aside.

7. At this point you can remove the existing piston and

exchange it with the other piston, installing the piston
with the taper of the piston towards the muzzle. Or, to
continue disassembly, remove the gas piston, gas sleeve
and sleeve spring by sliding them forward off of the
magazine tube one at a time as explained in the complete
Super X2 owner’s manual. Your gun’s barrel is fully
disassembled (Figure 2).

8. For disassembly and reassembly of the trigger group and

other internal components follow instructions and
warnings in the complete Super X2 owner’s manual.

INISHES

Be especially careful when cleaning guns with Dura-Touch

®

Armor Coating and other special finishes. Always prevent
these surfaces from coming in contact with cleaning solvents,
barrel scrubbers and other strong chemicals. It is preferable
to clean these surfaces with a light gun oil containing no
solvents or with a damp cloth and mild dish soap (be sure to
keep water out of the action). When cleaning your firearm’s
bore and action, protect the external finishes from any
contact with chemicals used. Also, avoid any contact
between external finishes and other strong chemicals like
those found in DEET-containing insect repellents,
sunscreens, etc. Damage to Dura-Touch and other finishes
caused by chemicals is irreversible and unrepairable.
